I have an Amana dlg 330 raw.
The dryer lights initially then after about 2 minutes the gas goes out and the ignitor does not glow again. If I let it cool and turn it on 30 minutes later the same happens.
If I dixconnect the power to the cycling thermostat the gas stays alight and keeps heating.
The coils were replaced a few years ago along, what other tests can I do for the cycling thermostat?
Thanks

I have, for the 2nd time in 2 years, replaced the gas valve coils on my Amana dryer. Usually, intermittent (inconsistent) heat or no heat is caused by bad gas valve coils. They are one of the most common parts to fail and cost between 35 and 40 dollars for a valve coil kit and are easy to replace yourself. Remove the front of the dryer (or the bottom front panel, in some cases) and locate the gas valve. It is near the front, in most cases. There is a plate, held with 2 bolts, holding the coils on top of the gas valve. Remove the bolts and the plate, disconnect the coil wires from each coil and slide the coils off. Then place the new coils on top, hook up the wires, replace the retainer plate, and you should be back in business. Take note of which coil sits on which part of the gas valve. On my dryer, one coil has a 2 prong connector, and the other has 3 prongs. This should make it easy to determine which is which.

sounds like bad gas coils located on top of the gas valve,when the coils start to fail the ignitor will glow,the coils let the gas in until the coils heat up and then ignitor glows but no gas.when the coils cool down they might work again for a short time until they heat up and fail again.if the flame lights and goes out after like 30 seconds and goes out and keeps doing this you have a block either in the dryer or the vent line but it sounds like you have bad gas coils.unplug the dryer,get at the valve,pull off the wires going to the coils and check them with a meter,one should be open,just remove the two phillips screws pull off the cover and slide the coils up off of the posts,unplug them and put the new coils on,you'll see like a little piece of plastic on the top of the coils,this fits intoo the cover so they line up correctly and holds them in place,also on the larger coil there's a spacer on the post,if you don't see it look inside the old coil,poke out the spacer and slide it onto the post and then install the coil.

Hi,
If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat.

If your dryer heats when you first turn it on and after a few minutes it does'nt. check the ignitor to see if it is glowing. It should glow bright then you will hear a click and the burner will light. If the ignitor glows bright but you hear a click but no flame and if you watch this for several minutes and this process continues of glow then glow goes out no flame, then you have a bad burner coil. There are 2 black solenoids sitting on top of gas valve. One of them is shorting out after it warms up. Replace both solenoids. You can usually get them as a kit from parts store.

Watch the burner assembly, shortly after starting the
dryer the ignitor should begin to glow. If it glows for several
seconds (up to 15 seconds) and then goes out, then the problem
is probably the solenoids (coils). If the ignitor glows and stays
on, then the problem is usually the flame sensor.
